Need Help??

Awesome, thanks for the explanation.

What do you mean though by

Note that this aliases $_ to the scalar, but File::Find does not take advantage of that feature.

Specifically the part about not taking advantage of the feature. What features could be taken advantage of? Thanks

EDIT:

Oh wait are you saying that $a could be used like $_ (they become equivalent?). Or is there something else?
